How to Add a New Section

In _data/adase there are three files, nav_bar.yml, title_nav_bar.yml, and footer_nav_bar.yml, each responsible for, respectively, the links in the header, the same links in the header at the home page and also the links in the title page, and the links in the footer.

To add the link to a page into these lists, you need to first find the URL of your page. Look here, here, here, and here for how Jekyll builds the URLs of the pages, or simply build the site locally and find your page in the _site directory — the URL is the relative path to the page. Then, add the URL into the respective *nav_bar.yml file.
